Cylindrical Style EMI Filters
GK Series – .375/.410 Dia.
Hermetically Sealed – Circuits Available – C, L, π, T
APPLICATIONS
The GK series offers effective filtering from
30 KHz to 10 GHz. Glass sealed for
hermeticity, this series is impervious to
high moisture, solvents, or other severe
environmental conditions commonly
encountered in military applications. It
is designed for bulkhead mounting in
a slotted hole with nut and lockwasher
supplied.
The “L” and “T” configurations are designed
to provide effective attenuation over a wide
range of circuit impedances. For current
ratings under 10 Amps toroidal wound
inductor elements offer increased filter
performance and protection against circuit
transients. Data showing the actual
inductance versus various levels of DC or
AC bias current are available as well as the
attenuation in any combination of source
and load impedances.
Alternate lead configurations or special
capacitance/inductance values may be
ordered.
Custom packages or filter arrays utilizing
the GK series can be furnished.
CHARACTERISTICS
• .410 Dia. version (HK) meets or exceeds the applicable
requirements of MIL-F-28861/2,/3,/4,/5. See QPL listing.
• Glass hermetic seal on both ends.
• Wound toroidal inductor used in current ratings up through
5 Amps. Ferrite bead inductor used in 10 and 15 Amp
designs.
• High DC current rating: 15 Amps.
• High capacitance values available.

Actual measurements may vary due to internal capacitor
resonances and other design constraints.
NOTE: All “L2” circuits are also available as “L1”.
Insertion loss and other parameters are identical.

Decimal point values indicate capacitance in microfarads. Non-decimal point values indicate capacitance in picofarads.
2
Insertion loss limits are based on theoretical values.
Actual measurements may vary due to internal capacitor resonances and other design constraints.
NOTE: All “L2” circuits are also available as “L1”. Insertion loss and other parameters are identical.
Only the part number changes (e.g., L2 = GK2LA-S04, L1 = GK2LA-R04).
